Abstract
A closure assembly for piercing and creating access to a container whose mouth is normally sealed by a thin membrane applied to a rim of the container.
Claims21
A closure for a membrane sealed container, said closure comprising:
- an annular side wall;
- a top wall connected to said annular side wall, the top wall having a center outer surface;
- an annular ring extending upward from the top wall,
- a recessed surface disposed between the annular ring and the center outer surface, the recessed surface configured to form a channel for receiving the top rim of the membrane sealed container when the closure device is inverted and pushed against the top of the membrane sealed container;
- at least one piercing member disposed on the center outer surface in spaced apart relation to the annular ring, the at least one piercing member having a first height above the center outer surface;
- at least one directional plow disposed on the center outer surface separate from and in spaced apart relation to the at least one piercing member, the at least one directional plow having a second height above the center outer surface that is less than the first height of the at least one piercing member.
3 more elements
A container comprising:
- a container body defining a pour orifice, said pour orifice fluidly sealed by a pierceable membrane;
- and
- a cap member constructed for attachment to said container body adjacent said pour orifice, said cap member comprising:
- an annular side wall;
- a top wall connected to said annular side wall,
- an annular ring extending upward from the top wall,
- a recessed surface extending between the annular ring and a center outer surface to form a channel for receiving the top of the membrane sealed container when the closure device is inverted;
- at least one piercing member disposed on the center outer surface in spaced apart relation to the annular ring, the at least one piercing member having a first height above the center outer surface, the at least on piercing member configured to pierce the pierceable membrane when the cap is inverted and rotated on top of the container body adjacent the pour opening;
- at least one directional plow disposed on the center outer surface separate from and in spaced apart relation to the at least one piercing member, the at least one directional plow having a second height above the center outer surface that is less than the first height of the at least one piercing member, the at least one directional plow configured to maintain tension on the pierceable membrane.
6 more elements
A closure assembly for use with a membrane sealed container, said closure assembly comprising:
- a closure shell having an annular side wall;
- a top wall connected to said annular side wall, the top wall having a center outer surface;
- an annular ring extending upward from the top wall,
- a recessed surface disposed between the annular ring and the center outer surface, the recessed surface configured to form a channel for receiving the top rim of the membrane sealed container when the closure device is inverted and pushed against the top of the membrane sealed container;
- at least one piercing member disposed on the center outer surface in spaced apart relation to the annular ring, the at least one piercing member having a first height above the center outer surface;
- at least one directional plow disposed on the center outer surface separate from and in spaced apart relation to the at least one piercing member, the at least one directional plow having a second height above the center outer surface that is less than the first height of the at least one piercing member;
- a closure core removably attached in the interior of the closure shell, the closure core configured to engage with the top of the membrane sealed container.
